Do you know or does anyone know the name/developer of the product for pocket pc? Is there a BLACKBERRY version?

According to the developer's website, you pay for the ability to download your ringtones. You have to do it one ringtone at a time. So, yes, it works on a BlackBerry.

UPDATE: I had some credit to use over at Handango so I decided to purchase HollerID. The ringtones come in both male and female voices, human and electronic. They also provide some ringtones that once you listen to them you'll understand them but those around you won't. After purchasing, you're taken to a link to download something, but it isn't anything you need. It's literally just a message that says you need use the URI in the e-mail.

The download process went fine and the tones work just like any other ringtone would.
